To all whmn it may concern.-

Be it known that I, ALFRED, L. MOORE, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in WVagons, of which the following is a s ecification.

My invention re ates to that class of wagons having a front bolster provided with a king-bolt for connecting it with the axle and having an axle provided with a bolster-supporting membersuch as a sand-board or lower bolster-upon which the top bolster is mounted.

The principal object of my invention is to provide a simple, economical, and efficient means for connecting the bolster or bolsters of a wagon with the sand board or lower bolster, and thereby with the axle or axles.

Other and further objects of the invention will appear from an examination of the drawings and the following description and claim.

The invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an end elevation, partly in section, of the front portion of a wagon provided with my improvements; Fig. 2, an enlarged detail view of the upper collar for the king-bolt; Fig. 8, a plan view of the same; Fig. 4, an enlarged detail view in central sectional elevation of the connecting bearing sleeve or collar which connects the top bolster and its bolster-platewith the lower bolster or sandboard and its bolster-plate and forms a bearing for the king-bolt and for such bolsterplates; and Fig. 5, a plan view of the sleeve or collar shown in Fig. 4.

In constructing an axle andbolster and bolster-supporting means in accordance with my improvements I provide an axle a, upon which is mounted a bolster-supporting member b in the form of a lower bolster or sandboard, which is connected to the axle by means of bolts 0, cl, e, and f, which bolts also pass through the interposed frame members and h. A lower bolster-plate "L is mounted on the bolster-supporting member or sandboard I) and provided with a central perforation for receiving the king-bolt and bearing sleeve or collar hereinafter described. A top bolster j is mounted upon and supported by such bolster-supporting member or sandboard and provided with a top bolster-plate It, which rests upon the lower bolster-plate i and is provided with a perforation which registers with the central perforation in the lower bolster plate. This upper bolsterplate is secured to the bottom side of the upper bolster by means of boltsZ, having heads on their lower ends which are countersunk into the bolster-plate and similar heads on their upper ends which are countersunk into the bolster top plate m.

A connecting and bearing sleeve or collar 7% is mounted with its lower end countersunk into the bolster-supporting member or sandboard I) and its upper end extending through perforations in the upper and lower bolsterplates and into the upper bolster, so as to permit the upper bolster and bolster-plate to rotate upon such sleeve. The lower end of this bearing-sleeve is provided with an enlarged annular shoulder portion 0 and laterally-extending lips 10. This enlarged annular bottom portion of the sleeve extends into a countersink in the sand-board, and the lips are depressed into the body portion of the sand-board. The upper surfaces of the annular enlarged shoulder portion of the sleeve and of the laterally-projecting lips are thus engaged by'the bottom bolster-plate, and the sleeve is held firmlyin place by means of such bolster-plate. The relatively small annular upper portion of the sleeve extends, as already suggested, through the perforations in the upper and lower bolster-plates and into the ody portion of the upper bolster, and a king-bolt g extends through the axial perforation in such sleeve and through vertical central perforations in the upper bolster, the lower bolster, or sand-board portion, and the axle.

An upper metallic bearing collar or sleeve r is provided with laterally-extending lips s and mounted in a countersink in the upper surface portion of the top bolster. A tapered countersunk portion 15 and central perforation to admit and engage the king-bolt, which is provided with a tapered head 1). A top plate m is provided with a perforation through which the king-bolt extends, the edges or walls of such perforated portion being bent downward or countersunk to correspond to the pitch of the tapered head of the king-bolt, so that the collar is securely held in place by the top bolster-plate and the head of the bolt is in engagement with the collar and with the inwardly-bent portions of such plate.

By the above arrangement it will be seen that the lower bearing-sleeve n forms a bearing or pivot for the upper and. lower bolsterplates and is held firmly in position by the lower bolster-plate and that such sleeve also forms a long bearing for the king-b0lt and is adapted to prevent the king-bolt from. coming into engagement with the upper and lower bolster-plates, so that all tendency to shear the king-bolt is practically removed. It will also be seen that the upper collar prevents the upper portion ofthe king-bolt'from wearing awaytheupperbolster and that-the kingbolt is prevented from becoming loosened by wearing awayeither the upper bolster or the lower bolster or sand-board member. The collars are both :firmly held in place, the lower one by the lower bolster-,plateand the upper one bythe bolster top plate m. The top bolster and its bolster-plate are prevent ed from having any undesirable play with relation zto the lower bolster-plate, and alllof the parts are prevented from being worn away by the king-bolt or by frictional contact with each other, such as would occur if the such bolstersupporting member and the lower side of the bolster, a bearing-sleeve provided with an enlarged lower end portion extending into the bolster-supporting member and in engagement withthe under sidelof the lower bolster-plate, means for securing such lower bolster-plate and thereby rigidly securing the bearing-sleeve in position, the upper bolster-plate being secured to the upper bolster and provided with a perforation into which the upper end of such bearingsleeve extends, a metallic collar encircling theupper end of the king-bolt, anda bolster top plate extendingover such collar and provided with a perforation for receiving the king-bolt.
